[QUOTE="NDMstang65, post: 6102997, member: 544576"] I'm talking for a speaker dude...i'm well aware of what aluminum does on aircraft (757 that I worked on stretched 2" nose to tail during the ascent that we gathered data from and we didn't fall out of the sky). I've done consulting work for Nasa and Boeing on noise control and aircraft panel analysis at Virginia Tech in the Mechanical Engineering department. Throw an aluminum cone in an extreme vehicle using a 6th or 8th order series tuned bandpass or a super street vehicle and see what happens to it. There is a BIG reason why nobody uses it...best of luck if you are going to try to change that curve. You could make it 1/8" thick and it would still bend it like a pop can. There is a reason why bridges bend..and there is a reason why aluminum truck beds are made to bend too. A cone on a speaker is waaaaaaaaaaaaaaaaaaaay different then any of that. [/QUOTE]
